HackerOne aims to review and approve each newly submitted tax form within 48 business hours. However, certain scenarios may necessitate additional time for review. These scenarios include, but are not limited to, instances when identity details are incomplete or when identity details are discrepant from previously submitted tax forms. If this occurs a member of HackerOne’s team may reach out to you to request additional details or request your tax form to be updated with more information.
